Barao probably could school all of them in muay thai. TJ beat him at MMA, not muay thai or anything else. Have you seen the sparring at Nova?
If you really want to dissect it, TJ landed one big shot, couldn't finish it, and Barao was on another planet rest of the fight. It's like Jones vs Shogun or Cain vs JDS 2+3, Shogun said himself he was not in that fight from the moment that knee hit him. But who's shown to be the better striker throughout their career? It's MMA.
Put these fights aside and actually look at all performances of the fighters in question, it's obvious who the more technically sound strikers are. In his second to last sentence Aldo is stating a fact, he's not being salty.
